A tool management device for managing tools detachable from a plurality of tool stations provided in a turret of a machine tool includes a display controller controlling a display to display tool information related to one or more tools attached to each of the plurality of tool stations. The display controller switches, on a single screen, between a deployed state of deploying and displaying tool information related to all tools attached to one of the plurality of tool stations, and a folded state of folding and displaying tool information related to only one predetermined tool among the all tools attached to the one of the plurality of tool stations.

Machine tool and machine tool management device with tool state display

A machine tool () includes a tool information storage () storing therein used tool information for, when an NC program execution part () executes an NC program, specifying a tool used for machining, and a magazine operation panel () includes an announcement part () for announcing an alarm to an operator. When receiving an operation signal from an input part () while the NC program execution part () is executing an NC program, a tool change control part () checks the used tool information stored in the tool information storage (), and in the case where a tool held by a tool pot () corresponding to the operation signal is not used for machining, moves the tool pot () to a tool attachment/detachment position (), and in the case where the tool is used for machining, causes the announcement part () to announce an alarm indicating that it is unavailable.

An interference checking devicechecks, during machining using an NC machine tool, interference between structures of the NC machine tool, a tool and a workpiece, and includes an interference check processing unitvirtually moving models and checking the occurrence of interference based on a position control signal from a numerical controller, and an operation effect degree evaluating unitevaluating the degree of an effect of an operation on a possibility of the occurrence of interference. When a predetermined operation is performed during machining of a workpiece following a first workpiece, the interference check processing unitmoves the models at intervals determined based on the degree of the effect evaluated by the operation effect degree evaluating unit

Interference checking device

A controller for a machine tool has a program storage section in which an NC program is stored, a program analyzing section analyzing the NC program block by block in sequence and extracts operation commands for a feed mechanism, an execution control section executing the extracted operation commands and thereby controlling the feed mechanism, e program editing section changing the NC program, and a change information storage section in which change information relating to the changed portion of the NC program is stored. The execution control section, when executing the operation commands, checks whether the block of each operation command is the block immediately preceding a block relating to the changed portion, and when judging that it is the immediately preceding block, temporarily stops the operation of the feed mechanism before or after the execution of the operation command.
